Mutr0lblackhat@gmail.com Screenlocker

Mutr0lblackhat@gmail.com Screenlocker (a.k.a. Cryptodevil Screen Locker) is one of these computer infections which cause many problems if they enter computers. The successful infiltration of this malicious application does not mean that your files will be encrypted or you will start seeing tons of commercial ads. Instead, you will find an irritating red window opened in full-screen on your Desktop. It does not, technically, lock the screen because keyboard shortcuts (e.g. Alt+Tab and Win+D) which minimize/close this window still work, but this, without a doubt, does not mean that you can do nothing about its presence. Sooner or later you will find it extremely annoying too because it will not allow you to access programs and files located on Desktop. Luckily, it can be deleted manually without special tools and special keys, so ignore the message located on this screen-locking window claiming that a key for unlocking the computer needs to be purchased.

The appearance of a red window “Your Computer Has Been Locked” is directly linked to the entrance of the malicious application called Mutr0lblackhat@gmail.com Screenlocker.

It is, of course, not the first malicious application which has been developed to fulfill this objective.

To be honest, it is not very likely that this infection can erase files from your PC. On top of that, the annoying window from Desktop can be removed manually too, so there is no point in sending $1000 to cyber criminals too. Better focus on the deletion of malware instead – more information about its removal is provided in the 2nd part of this article.
